XML Benchmark is a C/C++/Java XML parsers benchmarking toolset. Supported parsers include LibXML2, Xerces, Oracle XDK, Expat, RXP, QT, and Sun Crimson. Benchmarking fields include parsing (native, SAX, DOM), DOM manipulation, schema validation, XSL transformation, and XML signature and encryption.
XML Processing Benchmark for Java measures and compares the performance of XML Processing programs. It considers operations such as parsing, transformation, validation, encryption and decryption, custom access and manipulation, or any combination of these applied to one or more XML files or byte streams. It consists of code to carry out certain XML processing tasks, code and script to run the processing tasks and report performance measurements, and a framework to plug code and scripts in for processing. It also allows for XStat Processing, which collects certain statistics about an XML file.
XSDBench is a W3C XML Schema benchmark that compares the performance of validating XML parsers. It measures validation throughput, statically-linked test executable size, and, where possible, peak heap and stack memory usage during parsing. Tests and results for the following parsers are provided: Apache Xerces-C++, CodeSynthesis XSD, GNOME Libxml2, Microsoft XML Core Services (MSXML), and Oracle XDK.
Zoom is a low-overhead graphical and command line profiler for Linux. Profiles are system-wide, precise down to the instruction level, and capture complete backtraces of C/C++/ObjC/Fortran/Assembly code. This lets you see exactly where time was spent, what code was running (user or kernel), and how that code was called. Drill down into a specific symbol, and Zoom shows source and assembly annotated with general and processor-specific tuning advice. It saves profiles as a single, self-contained session file that can be emailed or attached to bug reports. This lets you share what you find with colleagues or archive it for later review. Zoom also supports remote network profiling and scripting, making it ideal for embedded or server systems and automated workflows.
Bandwidth is primarily a memory bandwidth benchmark, but it can also measure network bandwidth. It measures the maximum memory bandwidth of each part of the memory system, including main memory, L1, L2, and L3 caches, framebuffer memory, and register-to-register. For many tests, it performs both sequential memory accesses as well as random memory accesses to provide a more real-world performance estimate. The tests support Linux (Intel), Windows/Cygwin, and Mac OS X. Its core routines are in assembly for x86 and x86-64 architectures with both SSE4 and AVX support. Bandwidth also includes automatic graphing of the results, stored to a BMP image file. The network bandwidth tests support Linux, Mac OS X, and Windows/Cygwin.
bonnie is a classic file system and storage device benchmark. It tests for linear character-based and block-based reads and writes, and the rewrite pattern. It also does a seek test. While other benchmarks do more sophisticated tests, bonnie is a very reliable and portable program that is suitable for basic testing. Optionally, you can test the operations with direct I/O (O_DIRECT on Linux).
Bonnie++ is based on the Bonnie hard drive benchmark by Tim Bray. The most notable features that have been added are support for >2G of storage and testing operations involving thousands of files in a directory. This program is used by ReiserFS developers, but can be useful for anyone who wants to know how fast their hard drive or file system is. It now includes ZCAV in the package. This program tests the performance of different zones on the hard drive. ZCAV has been released separately before but will now only be released as part of the Bonnie++ suite.
bytecounter is a program that copies data while showing a status line indicating the data rate and estimated time remaining. Optionally, it retries on errors, which is useful for recovering files from bad media. It designed to be used "in-between" two programs to measure rate of data flow, such as between the output of a tar command and a file. It works with files, floppy disks, hard disks, terminals, tapes, CD-ROMs, FIFOs, and anything else you can think of.
